Will these Washingtonias survive my 8B winter unprotected?

[palmofmyhand]

I want to hear everyone’s opinion. I have these 3 Washingtonias that I planted in the spring and our loving their new homes in the ground with their mulch and lava rock insulation. I want to hear all opinions, I will send $1 to each person on Cash App that was right once spring comes back around.  For a little bit of extra information they all survived a 29F night while still potted in February. The first one took no damage at all and the second two had very very slight browning damage that was all trimmed away and bounced right back. I live in Augusta, GA- Grovetown to be exact.

If we have an average winter, they will defoliate in the low-20's, °F. Be prepared to wrap them. Christmas lights and bubble wrap.

Watch the forecasts. Mid to late November, cut off the leaves and wrap.

[Mishaq]

I reckon, even if they defoliate, they will grow back and be full again by this time next year. But lets wait and see what happens

Only time will tell . There's no guarantee for anything and that all depends on the palm's genetic.  Augusta is in zone 8b that means Robustas aren't going to be your ideal palm if you look for a palm that you can enjoy for many decades ,unless yours share a large amount of Filifera genes . Since your palms are fairly young it's impossible to tell how well they will handle your winters at this moment  Their true cold hardiness comes with age. I have one Robusta growing in the front yard for 3.5 years. It went through a few mid upper teens quite a few times during that time.  Defoliated every single year so far but came back strong.  Robustas cold hardiness is hard to determine while some might get killed in the mid teens  some others can survive single digits . Over here in Texas we can say a lot of weak Robustas didn't survive temperatures below 15 degrees back in 2021 . It's going to be a hit or miss palm for you.

Ok I just looked up some record lows by year for Augusta . I can assure you , unless your Robustas are highly Filifera leaning , that they aren't going to make it that long.  Two to three 8a winters occur every decade in your area. That's going to be a tough challenge without protection to keep them alive.  You'll be way better off with Sabal Palmettos , trachycarpus fortunei and sabal minor if you want to be sure .

This^^^^But could survive a few years depending on weather looking at your temps

With the lack of hurricanes, I am going to go out on a limb and say the SE is in for some winter.

Unprotected, I say they are goners

Thanks, I have 6 trachycarpus fortunei, a chamaerops humilis pair, and four sago palm cycads that I am sure will all be great as well. I have seen a handful or so of washingtonias in my Augusta area that are pretty big as well. I was really hoping I could leave them unprotected but I am thinking I really might have to use protection methods. I had four phoenix sylvestris die after this last winter while unprotected and got them comped under warranty. We had a rough winter this time but I was really hoping we could get lucky with a light one this year.

There's nothing wrong with zone pushing.  The question you have to ask yourself is what am I going to do with the palm when the time comes when the palm simply gets too tall to protect?  You aren't going to dig out a 10 foot trunk with a shovel by yourself! You know I see a good number of people on here zone pushing small palms like Butia Oderata etc but Robusta grow extremely tall in a short time .  I planted one when I had no knowledge about palms and I regret it. I do see a lot of Robustas growing around here and they survived Palmageddon in 2021 but I can't tell you if mine can survive our extremely cold rare artic blasts yet . I'm already willing to pay for removal in case it gets killed one day . After the time talking to people here I gained more knowledge and now I'm at a point where I only grow palms that can handle at least a zone and a half lower.  Trachycarpus fortunei is a beautiful palm . I'm growing two so far but thinking of planting a third one. 

[MarcusH]

I bought this palm 3.5 years ago and she was smaller than yours.  Defoliated every year.  Just showing you how fast they can grow .  I put a water bottle in front of the trunk for comparison.  Trunk is getting really fat .

[NC-Key-Bar]

They will be fine.

[JohnAndSancho]

It depends on how cold it gets.

No hay nada malo en empujar la zona. La pregunta que debes hacerte es ¿qué voy a hacer con la palmera cuando llegue el momento en que simplemente crezca demasiado para protegerla? ¡No vas a desenterrar un tronco de 10 pies con una pala tú solo! Sabes que veo un buen número de personas aquí empujando la zona de palmeras pequeñas como Butia Oderata, etc., pero las Robusta crecen extremadamente altas en poco tiempo. Planté una cuando no tenía conocimientos sobre palmeras y me arrepiento. Veo muchas Robustas creciendo por aquí y sobrevivieron al Palmageddon en 2021, pero aún no puedo decirte si la mía puede sobrevivir a nuestras raras ráfagas árticas extremadamente frías. Ya estoy dispuesto a pagar por la eliminación en caso de que muera algún día. Después del tiempo hablando con la gente de aquí, adquirí más conocimiento y ahora estoy en un punto en el que solo cultivo palmeras que pueden manejar al menos una zona y media más baja. Trachycarpus fortunei es una palmera hermosa. Estoy cultivando dos hasta ahora, pero estoy pensando en plantar un tercero.

I would love to buy a potted Jubaea Chilensis but nobody is cultivating them to the point of having them up for sale in a 3 gallon size that’s readily available. I wish somebody started a big Jubaea Chilensis growth project and started mass producing them that would be pretty cool.

[Hu Palmeras]

You should get a large one and protect it during the winter by transplanting it into the ground. This way, it will establish itself very well. These palm trees are for cold weather, but they must take root very well.

@marcus couldn’t you find a filifera to plant? I would think those would absolutely thrive in San Antonio and even the arctic blasts there wouldn’t faze it much. If they can thrive in west Texas zone 8A they should do great there.

Yes, they thrive in San Antonio and there are a lot around.  Currently I have 4 planted in the ground.  Here's one I grew from seed 3 years ago. It's the one to the left.  The other ones grow in the backyard.  I also grow a couple of Trachycarpus fortunei and Butia Odorata in the backyard. 

[PalmatierMeg]

Robustas are iffier than filibustas and filiferas. My robusta grew gangbusters for me in my sweltering summer climate. Filiferas prefer dry climates which GA is decidedly not. I suggest a filibusta with predominantly filifera genes.

Donate my $1 to John

Washingtonia are happiest in 9A+ but can handle average 8B winters with some damage. When you get a 8A winter they might be in trouble. That said there are many survivors during 10F temps last winter along the northern gulf coast and that surprised me a bit especially since it was a wet/snowy event.

After checking your yearly lows out there in San Antonio that gives me more hope of survival unprotected although I am still considering the christmas tree lights method. Beautiful palm by the way.

[DreaminAboutPalms]

I say go for it. Won't last forever, but plenty of examples around Augusta of Robusta that have survived semi long term. Sadly I believe most of these are dead now.

Guaranteed the foliage will burn. That's why you should cut it and as a minimum, wrap. Wrapping can keep the bud dry.

Thank you. She gets good care.  With Robustas you never know what you get but the vast majority are Filibustas nowadays unless you can buy them local somewhere where you see pencil thin Robustas with gloss green fronds. I'm not sure if pure Robustas have any fiber on their fronds I guess someone else could chime in.  I know mine is a Filibusta with some Filifera in it.  The fronds burn in the low 20s but the crown grows back so quickly.  

[ryjohn]

Yes… easily.  Based on my experience in (harsher) 8B north Louisiana
